Application filed August 17, 191. Serial No. 115,402.

To all 'whomt't may concern Be it known that I, THoR RAJE, a citizen ofthe United States, residing at Los Angeles, in the county of Los Angelesand State of California, have invented new and vuseful Improvements inTalking Machines, of which the following is a specification.

My invention relates to talking machines andthe primary object thereofi's to provide a multiple record machine arranged to play records ofsubstantially large diameter and to support a plurality of such recordsin'position for successive use.

Another object is to provide a multiple record talking machine arrangedto support a plurality of large annular records in operative position'without substantially increasing the size of the machineA over the sizesof-machines in general-use with other types of records.

A further 'object of this invention is' to provide a machine capable ofplaying a series of records selectively, one at a time, in successiveorder and capable further, of repeating a selected record at the optionof the operator.

4A further object is to provide means for rendering lengthy musicalcomposition which cannot usually be rendered on other types of machines.

n talking machines of known construction it has been found impossible tocompletely record certain lengthy musical compositions owing tothe factthat records of sufficient size cannot be made with racticability. Suchcompositions have t erefore been revised and changed to adapt them forreproduction on talking machines, and for this reason the value of therecord, especially to students of music, has been greatly depreciated.To overcome this objection, the present invention has 4been designed andcontemplates preferably the provision of a plurality of records of novelconstruction' mounted upon a mandrel in such a -manner as to permit ofthe reproduction of eachf record in succession whereby any musicalcomposition may be played in its entirety.

The invention further contemplates lthe utilization and saving-of Spaceby providing a mandrel ofhollow construction to enable the mounting ofthe drivingmeans, includ` ing a motor therein and means -forremoving themandrel Jfrom the casing. This v con struction permits the use of amotor ofrelaI-r tively large capacity. lBy this conetraction k raaressieu. j

the mandrelsmay be employed as files or..rv

holders for records while not being used. Due to the relatively greatdiameter and size of the mandrels, they also act as a fly wheel for themotor.

Another object is the provision of a motor which may be used to operateany mandrel selected. To this end a motor housed in a suitable casing isarranged to be detachably secured within a mandrel.

A further object is to provide a meansforv v identifyingA the recordmounted upon the mandrel, and to this end a suitable index is carried bythe machine cabinet and has associated therewith an index fingerextending from the sound box carrying lever so t/hat the latter may withfacility be adjusted toa position to play any desired record of theseries mounted upon the mandrel.

A still further object is the provision of an adjustable automaticrepeat device of novel construction carried by the cabinet and arrangedin the path of movement of the sound box carrying lever and actuated bycontact therewith, to lift the sound box from .engagement with therecord groove, return l'the same the width ofthe record just played andthen lower said sound boX intoy contact with said record.

The invention. is illustrated in what is now believed to be thepreferred form, wherein the machine comprises a cabinet 12 generally ofordinary construction and having suitably mounted therein a. relativelylarge mandrel 1,3 preferably ofhollow construction. This mandrel is madehollow in order to economize space, and has detachably mounted in oneend thereof the usual spring motor which is conventionally illustratedat 14, and is provided with a housing. i shaft 15 extends from thehousing beyond the rear end of the mandrel, and is square at the end toengage a square slot in frame member 16. The slot is of bayonet form asindicated by 17 to permit insertion and removal of shaft 15. At thefrontend of the motor is a winding arbor 18 in alinement with shaft 15.Arbor 18 is rotatably mounted Cin a bayonet slot 17 in a frame member19, and is square at. the end for receiving the socket of a windingcrank 20.

Suitable ratchet and pawl mechanism may be provided for winding themotor so that when operating the housing will rotate with respect toshaft 15. The specific construc-` tion of the motor is not a materialpart of my invention exY pt in so far asl described and may be varigd inaccordance with constructions well known in the motor art. The space forthe motor, however, is such that a motor of large capacit,7 and.'greatpower may be used. The motor" housing has a cylindrical portion 22, isdisposed in atubular opening 24 on the end of mandrel 13 and is arrangedto frictionally engage the walls thereof with the flange 23 overlayingthe end wall 25 of the mandrel. This provides a construct-ion wherebywhen a mandrel is removed from the cabinet the motor may beVA detachedand inserted in another mandrel. The entire mandrel is removed byraising it so that shaft 15 is at the upperv part of the bayonet slot 17in frame 16 and arbor 18 is at the upper end of theV bayonet slot 17 inframe member 19, then pulling the mandrel forward removing shaft 15 andarbor 18 from their respective slots.l

Rotary movement from the mandrel 13 is transmitted by means of frictionor gear teeth at the end ofthe mandrel to a pinion 26 carried by frame19 interiorly of thel| cabinet7 said Apinion 26 meshing with 4a largergear 27, the shaft 28 of which proi jects upwardly through the. top ofthe casing and is provided at itsupper end with a bevel gear 29 meshingwith .a similar gear 30 carried by the screw shaft 31 which extendsacross the top of the casing or cabinet.

guide rod 32 is also mounted upon the top `of vthe cabinetlongitudinally of the mandrel 13 in parallel relation with 31, and hasmounted thereon the sound box carrying lever 33 carrying the sound box34 at its forward end and provided adjacent its rear end with a nut 35which meshes With the screw shaft 31 to advance the lever 33 across thetop of the cabinet. The sound box 34 carries a flexible connection 36,one

end of which projects into the adjacent end of the usual tone arm 37connected at its other end by a swivel joint 37 to the sound amplifier38 of ordinary construction, and the forward end is pivoted at 36 tosound box 34. 'The rear end of the lever 33 carries an index plate orstrip 40 containing suitable indicia to indicate which record is beingtraversed by the sound box 34. Through the medium of this index anyrecord desired vmay be reproduced by adjusting the lever 33 and theindex finger 39 to the number of the plate 40 indicating the number ofthe record desired. .Y

The mandrel 13'is preferably provided with a covering 41 of felt uponwhich is adapted to be mounted a plurality of records 42 of novelconstruction. By referring to Fig. 3, it 'will be seen that each of therecords 42 preferably consists of a ring member or annulus whose axis orwidth is relatively Ishort asV compared to its circumference ordiameter. Each of the records 42 as shown in Fig. 3 is of approximatelythe same width, h utit will that theY width thereof is arbitrarily andmay be regulated in accordance with the length of the composition to bereproduced. The records are all preferably tapered as indicated, andeach is provided upon one edge with a flange 43 which receivesthereinthe adjacent end of the successive record, so that when all of therecords are in position on the mandrel' the same are nested to permitthe. travel of the stylus from one record to another. The flange 43 uponits rear surface is inclined or beveled slightly so'that the same willmerge with the adjacent record surface of the nearest record, it beingunderstood that the record groove is formed in the periphery orcircumference of the record. It will thus be seen from the foregoingdescription that when the records 42 are in position on the mandrel, thesound box 34 will travel from one record onto the other and in thismanner a continuous reproduction of a very lengthy composition maybeobtained, and all of the l records held on the mandrel may be playedin series without interruption.

Also, records of different pieces of music may be mounted upon themandrel, and when it is desired to play any one of said records thelever 33 be understood of coursetogether' with .the sound box 34 may beadjusted as'previously indicated. It will also be apparent that themandrel maybe employed Ain lieu 'of the usual record cabinet for storingrecords when not being used,l

and in this way a. saving of space is also accomplished. j fTheinvention also contemplates the provision of mechanism for repeating thereproduction of any record desired, and to this end there is mountedupon the top Iof ing rod 44 of approximately the same length" thecabinet forwardly of the guide rod 32 and parallel therewith, a suitablelsupportas the lguide rod 32. Slidably mounted upon the rod 44 is asleeve member 45 carrying at one end bevel gear 46fvvhic-h is vnormallyheld out of engagement with the bevel gearv 47 by means of a spring 48,the gear 47 being carried' bythe upper end of the shaft 49 which isdriventhrough the medium of the: gear 26. A contact element 50 isad-ljustable longitudinally of the sleeve 45 and secured in its adjustedposition by means of la cam 51 pivote'd to the element, and

adapted to engage said sleeve. This element 50' is eccentrically mountedupon the sleeve V45 so that a greater portion of the Weight of theelement 50 from the inner end of the compound curve 52 to thevouterextremity thereofis approximately the same as the l width of a record,and when the element 50 is in normal position .as shown in` Figs. 6 and10, saidcurve 52 is uppermost.

When it is desired to' repeat one of the records mounted on-the mandrel,the ele-.

mem-,.50 is adjusted along the sleeve 45 until the yshoulder formed bythe inner end of the surfacev 52 is a slight distance in ad- Y vance' ofthe end of the particular record `to be repeated. The shoulder 50l ofelement 50 is now in position to be engaged by a pin 53 depending fromlever 33. Pin 53 is provided withi a lug 54 forming a. shoulderthereon.` The shoulder on pin 53 rides on the eccentric lsurface ofelement 50 While the lug 54 bears against surface 52. As the lever 33which carries the said pin 53 progresses farther the element 50 andsleeve 45 are moved along rod 44 until the bevel gear 46 is in mesh withthe bevel gear 47 whereupon the sleeve 45 will be rotated and pin 53raised. At the initial rotary movement of the element 50 the lever 33 israised or elevated by reason of its contact with the eccentric surfaceof element 50, and this movement of said lever will disengage'the sound`box 34 from ther record groove. Further movement of the element 50 willficause the pin and lever 33 to slidev along the edge of the surface 52,and thus return said lever 33 toward. its position at the beginning ofthe record to be repeated. [Atsubstan-k tially the same time that thelever 33 starts moving backward, the spring 48 will 'force the sleeve 45along the rod 44and disengage the bevel gears 46 and 47 and continuedrotation of the sleeve 45`-will usually ensue due to the momentum giventhe same when the said vgears initially mesh. When the` lever 33 andsound boxy 34 have reached the beginning of the record, they parts arein the position shown in Fig. 7 .in 'full and owing tothe mounting offthe element 50 lwiththel greater portion of its Weight on one side `ofthe axis of rotation, said` element'l vWill-continue to rotate until thesame `a`s' sumes its normal position. Continued rotation of the element50 will, owing to the formation of the reduced end, disengage .itselffrom the lever 33 and permit the sound box 34 to'be lowered intocontactwith therecord. i f Y It will be apparentfrom the foregoing;V

description that the record maybe repeated as many times as desired4 byleaving. the

element 50 in its adjusted. position andlby' moving the same to the endof the sleeve145 the records may be played insuccession and withoutrepetitions. p y

In order to remove Land replace and change the mandrels, access is hadto the interior cabinet or casing through a door .55.

It is obvious that the mounting of a plurality of records on onevmandrelin my ma.- chine, obviates the necessity of continuous changes,namely,` the placing and i removing of each individual record beforeanother can be played. v The increased playing capacity of the motorremoves the objectionable .feature of continuous winding or the Ywinding in the middle ofthe playing of a record. The great majority ofinjuries and breakages of records is dueto thecontin.-v

uous handling in` moving, removing and selection of records for placingon themachine and in proper place inthe filing cabinet.

A governor 55is operated by means of 4a friction roller or gear 56,whichis driven by the end of -the mandrel `13 in aniaiiner similar to that ofthe pinion 26 on .the opposite end of the mandrel. This governor ispreferably of the usual type'and character ofthe ball governor andserves to regulate the speed of the mandrel 13. It is obvious that 4thespring motor may be wound by means of the crank 20 while the mandrel isin motion and the governor prevents excessive speed 'of the' recordsduring the 'wind'- ing operation. Rollers 57 are carried on the frames16 and 19 and contact with the lower-end portions of the mandrel.
